LED Low Bay Lights

LED low bay lights are overhead fixtures built for commercial and industrial ceilings between 8 and 15 ft, where a high bay would throw light too far. This category covers round UFO low bays and linear low bay lights in the lumen packages that suit workshops, warehouses, and retail backrooms.

LED Low Bay Light Selection Guide

A low bay is simply a high output fixture with optics tuned for a lower ceiling, so the light spreads wide instead of driving straight down. The split in this category is by form factor: Low Bay UFO LED Lights are compact round fixtures for open floor, and Linear Low Bay LED Lights throw a rectangular pattern that fits aisles and assembly benches. If your structure is taller than 15 ft, move up to LED High Bay Lights; for the broader plant catalog, see Industrial Lighting.

Low Bay Lights Matched to Mounting Height

Mounting height sets the lumen package, not wattage. Read your ceiling height across the table and the output follows.

Color, Controls, and Efficiency

For work environments, 4000K and 5000K dominate, with 5000K preferred where contrast and alertness matter. A CRI of 80 plus covers general tasks. Most commercial grade low bays include 0 to 10V dimming, and a plug in motion sensor turns a low traffic area into an occupancy controlled zone that dims to standby until someone arrives. Current fixtures deliver 130 to 150 lumens per watt, so a 100W low bay replaces a 250W metal halide unit with room to spare.

Mounting and Wet Location Notes

Low bays hang from a hook, pendant, chain, or surface mount depending on the structure. For damp or washdown zones in the same building, choose a sealed fixture or move to Vapor Tight Lights. Where the ceiling climbs above 15 ft, the beam gets too diffuse and a high bay is the correct call instead.

Frequently Asked Questions About LED Low Bay Lights

Mounting height. Low bay fixtures are designed for ceilings roughly 8 to 15 ft and spread light wide, while high bays are built for ceilings above 15 ft and concentrate output to reach the floor. Using a high bay on a low ceiling creates glare and hot spots.

Size by mounting height, not wattage. A 60 to 90W fixture suits 8 to 10 ft ceilings, 90 to 120W suits 10 to 12 ft, and 120 to 150W covers 12 to 15 ft. Confirm the lumen package and target footcandles for your task.

Most commercial grade low bays include 0 to 10V dimming as standard, and many accept plug in occupancy or daylight sensors so they dim to a standby level when the area is empty.

4000K gives a neutral white that suits most spaces, while 5000K gives a brighter, cooler light preferred where contrast and alertness matter, such as assembly and inspection areas.

A 100W LED low bay typically replaces a 250W metal halide fixture, and a 150W LED replaces a 400W unit, at the same mounting height with better light levels and no warm up delay.

Many carry damp or wet location ratings. For true washdown or high moisture areas, check the IP rating on the product page or choose a sealed vapor tight fixture instead.

DLC listed LED low bays commonly qualify for commercial utility rebates. Look for the DLC mark on the product page and check your local utility program.
